Maintaining a four-wheel-drive system involves periodic inspections and fluid changes, often including the transfer case, differentials, and axles. For example, a typical service might include checking for leaks, inspecting the condition of seals and gaskets, and changing the fluids in these components. The specific tasks and recommended intervals can vary depending on the vehicle’s make, model, and usage.
Regular maintenance of these systems is critical for optimal performance and longevity. Neglecting this type of upkeep can lead to costly repairs or even complete system failure, potentially leaving a vehicle immobile. Historically, four-wheel-drive systems were primarily found in off-road vehicles; however, their inclusion in many modern passenger cars and SUVs necessitates wider understanding of their maintenance requirements. Proper servicing safeguards against damage caused by wear and tear, especially during demanding driving conditions such as off-roading or driving in inclement weather.
